The 6 figure thing is a rule of thumb. I know there are plenty of cars out there that can beat a 600cc supersport, but overall they are incredibly few and far between.
For my area I know of 2 cars that didnt cost mondo money MSRP that can for sure do it. One is a sponsored demo car the other is an old muscle car, mad max style. Showed off for one of my friends on the freeway one time. He was on a 600 ninja with about a 20mph head start. The guy punched the throttle. My friend didnt even bother to try to keep up. Some rich, old, happy guy.
If you want a better firgure I'd say you'd be hard pressed to find a car that would cost less that 50k, list price with labor, to build that could run the sub 3 second 0-60 and 10 second range 1/4 mile.
Different worlds though. My little rocket cost less than 10 grand and I'd take a ride on it over a ride in a million dollar car.
